configure router isis metric-style wide level-1-2
configure router isis address-family ipv6 multi-topology
configure router isis address-family ipv6 enable
configure router isis address-family ipv4 enable no
2. Configure the IS-IS circuit:
configure interface ethernet 6/2.0 ipv6 address 2001:cada:c420:1702::2/64
configure interface ethernet 6/2.0 ipv6 router isis
configure interface ethernet 6/2.0 isis protocol no shutdown
3. Configure the static null route for aggregated range of PD:
configure ipv6 route fc0d:c420:ffff::/48 null 0
4. Configure the access list to deny redistribution range of PD routes that should not be advertised individually (also
known as prefixes for residential customers):
configure ipv6 access-list list1 deny fc0d:c420:ffff::/48
configure ipv6 access-list list1 permit any
5. Configure the redistributing routes in IS-IS. The PD routes for static commercial range should appear as IS-IS LSP. The
static route for aggregated range should appear as one IS-IS LSP for the entire range (null route).
configure router isis address-family ipv6 redistribute static level-1
configure router isis address-family ipv6 distribute-list list1 out pd
6. The following command line must be identical on all participating C4/c CMTSs. In particular, the metric type and
metric value in this command must be exactly the same for all C4/c CMTSs configured to handle the route collisions
that result from moving the commercial customers from one C4/c CMTS to another.
configure router isis address-family ipv6 redistribute pd level-1
7. Enable IS-IS:
configure router isis shutdown no
8. Enable PDRI (enabled by default):
configure ipv6 pd-route-injection
configure interface cable-mac 1.0 ipv6 pd-route-injection
9. Enable Prefix Stability (enabled by default):
configure ipv6 prefix-stability
Configuring Prefix Stability Using OSPF
There are two parts of this procedure. Part 1 is the configuration of the first C4/c CMTS.
